摘要：
An automatic mixing device, an actuating device removably mounted to the automatic mixing device and a retractable syringe having the automatic mixing device are provided. The actuating device has an initially compressed spring and a trigger member that initiates spring decompression to drive depression of a mixing plunger of the automatic mixing device. A seal located in the outer chamber is capable of axial movement upon depression of the mixing plunger, from a first position in sealing engagement with one or more apertures in an inner barrel to a second position intermediate the apertures and vents in an outer barrel. This allows depression of the mixing plunger to force a first substance from the outer chamber through the apertures to mix with a second substance in an inner chamber of the inner barrel. The mixed substance in the inner barrel is then delivered by the syringe with subsequent needle retraction.本發明揭露一自動混合裝置、一作動裝置可移動地安裝於一可縮回注射器的自動混合裝置，該作動裝置具有一初始壓縮的彈簧和一扣扳件使該彈簧減壓以驅動該自動混合裝置的一混合活塞降低，一密封件位於該外腔室內，該密封件能夠軸向的移動對應該混合活塞的降低，從該內筒的一個或一個以上的孔密封卡掣的一第一位置移到該外筒內的該孔和通風孔之間的一第二位置，允許該混合活塞的降低迫使一第一混合物質從該外腔室穿過該孔與該內筒內的一第二混合物質混合，該內筒內的混合物質由該注射器傳送及隨後注射針縮回。
